[Body composition in various nutritional conditions. Experimental study].
Body composition parameters were studied in different nutritional conditions in Wistar rats with experimental cancer. Results were submitted to statistical analysis. Under a hyperlipidic diet, fat increased in control rats and decreased in animals with tumor; sodium increase and potassium decrease was verified in rats with tumor. The NA/K ratio increased in both groups and the N/K ratio increased in rats with tumor under standard diet, but decreased in rats with tumor under hyperlipidic diet. Fat decreased in the animals with tumor under an aproteic diet, but sodium increased. Potassium increased in undernourished animals of both groups. The Na/K ratio increased in rats with tumor. A comparison was made according to two different standards: "fresh body weight" and "fat-free body mass". The parameters analysed showed no significant differences in body composition.
